slms Synth Complete.......Picutres

I just finished building my synth (the sound labs mini-synth) and i am very happy with the result. i would tell anybody that is slightly interested in building a simple synth to check this option out. you can input two contol voltages and a gate, but you dont need any of these if you dont want. it makes some pretty sweet sounds all by its self. i would like to find a mod so i can input a signal to the filters if anybody has a suggestion.

i have a complete parts list (with digi-key and mouser part numbers and prices) if anybody is interested i can post it.

here are some pictures:

let me know what you think.
enjoy,

Looks very nice! Is that a geiger counter case?

I would be interested in a parts list, since I have a minisynth PCB waiting for me. Thank you!

Ah man, that's a really cool little project. :thumb: That definately would turn a few heads if I walked into a session with that little puppy. Send me some info on it please.

Oh, I see. It's like a lunchbox-type case, or an ammo box, or something... Old test equipment, maybe?

It does look like a Geiger counter, though, doesn't it? :green:

Would love to see some drawings and a parts list. Also where did you get the case?

yeah, i just gutted a geiger counter that i bought off of e-bay (they go for pretty cheap and i figured it would make a scary project box).

it sounds awesome........it looks like it sounds, if that makes any sense. i played with it a little last night and got an endless amount of noises. but it was impossible to repeat the previous noise that i made.

i will probably just sample some of the noises but it also functions as a head turner.......people that have been comming over are gravitated towards it.

any body have an idea how to make a mod to put an audio signal through the filters?

here is my parts list (it is a little messy, i had a hard time copying it over).........double check everything because i copied this over from a couple of excel spreadsheets (i can email you the spreadsheets if you want).......................for a couple resistors and capacitors i couldnt find the right values so i just paralleled or seriesed them. you can notice this when i doubled part numbers.

oh yeah, i had another question............

how would i go about finding what voltage to supply that meter with? basically i thought it would at least be cool if the meter shot up and read "danger level" when the power was cut on. i also thought it might be cool, but probably really hard to do, is have the meter respond to the frequency of one of the oscillators.

any thought?

whoa! That is too cute!

You defininitely should try and make the meter read something though even if it's only voltage or something as long as it's in the red.
